Filed: 1941-02-28
Abstract: 547,501. Rotary conveyers. BEST, C., and MOLINS MACHINE CO., Ltd. Feb. 28, 1941, No. 2773. [Class 78 (i)] Means for guiding bullet envelopes delivered from a feeding machine has a pusher device which positively forces the envelope toward the outlet with its base foremost. The guides are of a known form consisting of vertical converging members 8 notched at 11 to receive channelled inserts 9, the nose of the envelope E entering one of the channels 10 to tip up the envelope and let it fall base foremost. The pusher consists of narrow plates 29 spaced apart less than the length of the envelope, and either pivoted about a rockable shaft or mounted on a reciprocating wedge. These plates 9 are actuated by a spring and roller connection to a cam-operated bar which also ejects the envelopes to the top of the shoot beneath the plates 29, and also provides a temporary rest therefor. A known form of detector is provided for limiting the quantity of envelopes accumulated between the guides 8. The front of the guides 8 is closed by a swingable door. Specification 547,500 is referred to.

Barrel and cylindrical hinges; double and multiple hinges.-In a wind-screen pivot the glass is flexibly mounted on the angularly-adjustable pivots by hinged clamps so as to reduce the liability of fracture due to the supports being forced out of alignment. Clamps 27, Fig. 1, have hinge lugs 29 and are adapted to be connected to a block 5, Fig. 2, by a hinge-pin which passes through the lugs 29, 24; these are closed upon and made to grip the glass by bolts 33, Fig. 4, passing through the holes 32.

Title: Improvements in or relating to the treatment of benzene hexachloride and to compositions containing such treated material
IPC: C07C17/395
Filed: 1945-02-12
Abstract: The odour associated with crude benzene hexachloride or g -isomer containing fraction thereof is improved by treating a solution of the benzene hexachloride with nascent hydrogen while maintaining the solution at a pH less than 10.  The product is suitable for incorporation in pest control compositions. Advantageously, the reaction between the benzene hexachloride and nascent hydrogen is interrupted before more than 50 per cent by weight of the chlorine content of the benzene hexachloride has reacted to form inorganic chlorine compounds, e.g. when between .5 per cent and 25 per cent by weight of the chlorine content has so reacted.  The nascent hydrogen may be generated by the interaction of a metal with a liquid containing a compound having reactive hydrogen groupings, e.g. by the interaction of metallic zinc with an aliphatic hydroxy compound. Specified aliphatic hydroxy compounds are: methanol, ethanol and glacial acetic acid which may be used admixed with acetone.  Other specified metals are sodium amalgam, tin and iron.  Suitably, a liquid sodium amalgam is reacted with a solution of benzene hexachloride in an aliphatic liquid miscible at ordinary temperatures in all proportions with water and containing at least 0.2 per cent by weight of water calculated on the weight of the benzene hexachloride. In examples: (1) crude benzene hexachloride in glacial acetic acid solution is treated with granulated zinc at room temperature for one hour, the reaction mixture is freed from zinc by filtration and the benzene hexachloride is precipitated by adding the filtrate to excess of water; (2) as in (1), but methanol and zinc dust are used to generate hydrogen; (3) crude benzene hexachloride in acetone solution containing a small amount of water is stirred for two hours at room temperature while in contact with sodium amalgam containing 0.2 per cent sodium and crude benzene hexachloride is recovered by heating the solution to remove acetone; (4) crude benzene hexachloride in benzene solution containing 0.15 per cent hydrochloric acid and 0.03 per cent water is treated with granulated zinc at 45 DEG  C. to 50 DEG  C. for 72 hours and the benzene hexachloride is precipitated by adding the liquid part of the reaction mixture to excess of water; the dry product is ground with 4 times its weight of gypsum to obtain an insecticidal dust.  Specifications 573,689 and 573,693 are referred to.
Patent GB-582431-A (GB)
Title: Improvements in footwear
IPC: A43B13/22
Filed: 1944-02-24
Abstract: Blanks for soles or heels are cut from a sheet of paper, textile or felted base material which has been impregnated to a greater or less degree with an artificial resin, with or without a plasticizer and colouring agent, and are afterwards moulded to shape.  The blanks may, alternatively, be impregnated after cutting them from a sheet of untreated base material.  A medicated solution may, if desired, be added to the impregnant.  A heel, or upper, may be moulded with a sole in one operation by assembling impregnated parts in a mould and applying heat or pressure.  The shoe parts may be impregnated on the outer face and edges only so as to leave, for example, the inner surfaces of the upper, softer; or a separate layer of felt &c. may be used for the inner surface of the upper to serve as a lining.  The upper may be of leather, or of fabric or other material with an ornamental pattern and coated with a transparent or translucent plastic material. Non-skid ornamental patterns may be formed on the sole or upper during the moulding process.  The artificial resin may be of the thermoplastic or thermo-setting types and may be in solution, dispersion or other liquid form, or it may be inserted in granular or sheet form in the moulds in which the shoe parts or complete shoe is moulded so that impregnation and moulding may proceed simultaneously.  Different kinds of resins may be employed as impregnant in different parts of the footwear.  In the case of a Wellington boot, to facilitate manufacture the upper leg portion may be united to the moulded lower leg portion in a separate operation.

Title: Improvements in fuel injection systems for internal combustion engines
IPC: F02M69/00
Filed: 1945-02-12
Abstract: 585,275. Regulating; spray carburetters. HOBSON (AIRCRAFT & MOTOR) COMPONENTS, Ltd., H. M., and GREENLAND, L. S. Feb. 12, 1945, No. 3451. [Classes 7 (iii) and 7 (vi) ] Three supplementary fuel conduits, controlled respectively by a slow-running valve 62, a weakto-normal cruising valve 53, and an accelerator pump 70, are operated automatically by linkage connected to a lever 52 in a fuel supply system in which fuel under pressure is delivered through a main conduit 12 containing a metering orifice 25 and having means for maintaining the pressure difference across orifice 25 as a function of the engine speed. Fuel delivered by a pump 11 passes through the metering orifice 25 whose area is varied as a function of boost and exhaust pressure by capsules 13 and 14 and of induction temperature by the Bourdon unit 23, the pressure across the orifice being arranged proportional to the square of engine speed by means of a centrifugal impeller 37 co-operating with a diaphragm 39 controlling the pressure regulating valve 40. The valve 62 is kept open to supply additional fuel at slow running by a finger 66. As the lever 52 is moved towards full throttle position, the valve 62 closes and at a predetermined position a finger 61 opens the valve 53 to allow additional fuel to flow through a conduit 54. Rapid movement of the lever 52 towards full throttle operates the accelerator pump 70, permitting a temporary additional supply of fuel through a conduit 69 to the main conduit 45. Fuel is injected into the induction pipe 15 through a valve 47, a cut-off valve 46 closing when the lever 52 is moved past the slowrunning position. The needle 24 is profiled to give additional enrichment at take-off and climb. In a modification, Fig. 2, the cruising enrichment valve 153 controls a bleed conduit 154 which bleeds fuel from the entry side of orifice 25 to the suction side of the pump 11, the valve being open at slow-running and closed at the desired enrichment point. In engines exhibiting high boost reversal, a weaker mixture is necessary at slowrunning, and modifications are described in which the slow-running valve controls a bleeding conduit from the entry or exit side of the metering orifice to the suction side of the delivery pump. Specifications 419,113, 566,323 and 567,239 are referred to.
